GARNET'I FREDERICK NORTON, or NGAIO, w'ELLiNe'roN, NEW ZEALANID.

STAY FOR CASEMENT-WINDOWS AND THE LIKE.

To all whom it may concern.

Be it known that I, GARNETT FREDERICK NORTON, subject of the King of Great Britain, residing at Ngaio, Wellington, in the Dominion of New Zealand, have invented a new and useful Improvement in Stays for Casement-Vi indows and the Like; and I do.

The invention consists in forming the usual stay bar with notches in one of its faces and in providing the usual swivel guide through which the bar slides, with a transversely sliding key wedge that is adapted to slide into any one of the notches in the bar and thus to lock the bar from movement through the guide.

In fully describing the invention, reference will be made to the accompanying sheet of drawings, in which Figure 1 is a plan, and Fig. 2 a side elevation of the improved stay. Fig. 3 is a sectional elevation through the swivel guide showing the stay bar in the unlocked con dition. Fig. 4 is a similar view, but with the bar locked.

A is the usual stay bar which at one end is pivotally attached to the bracket B that is fastened to the face of the casement sash in the well known way.

C are the square notches that are formed at desired intervals apart along the underface of the bar.

D is the swivel guide through which the free end of the stay bar A passes in the well known manner and which is pivoted upon the plate E secured to the casement sill, in such a manner that the guide may turn to suit the varying angles of the stay bar A as it is moved in and out through the guide with the closing and opening of the case ment. In this invention the guide is formed wit-h slots F in its side walls and with a Specification of Letters Patent.

dovetailed groove G in its base plate D. Extending, across in these slots and fitting into the groove, is the sliding key H the top of which is made of such a shape and size asto be adapted to fit into the notches C in the stay bar. The top of the central portion of this key is broken away, as at J in Figs. 3 and 4, for a sufficient length to correspond with the width .of the stay bar. When therefore the key is arranged centrally this broken portion will occupy a position eX tending between the side walls of the guide and thus allowing the stay bar to slide freely to and fro within the guide, as shown in. Fig. 8. When the'bar is moved so that one of its notches C is in a line with the key, the key may be moved along the groove in either direction and thereby cause its upper portion to enter the notch as shown in Fig. 4 and thus hold the stay from any movement through the guide.

Small knobs K are arranged to project upward from the top of each end of the key and these pegs engaging with the guide D will serve to prevent the key being moved right out.

The bracket D to which the bar is pivoted is provided with the projecting tongue 13 in which the end of the bar is pivoted. This tongue is made of such a size that it may pass into the guide D and it is also formed with a notch C. When the easement is lfully closed the tongue will pass into the guide and will then be locked therein by means of the key H and thus the easement may be securely locked in the closed condition.

It will be obvious that the slanting sides of the wedge-shaped key H will engage the corners of the notches C, in a manner to effectively prevent objectionable rattling of the window when the same is locked by my improved device. This feature is made more effective by having the key H disposed angularly or transversely to the axis of the bar A.

What I do claim as my invention, and desire to secure by Letters Patent is A stay for casement windows and the like comprising in combination, a bracket adapted for attachment to a casement, a swivel plate adapted for attachment to a casement frame, a tubular guide pivotally mounted on said plate and provided with oppositely disposed alined openings in its sides, a stay bar slidable through the guide and hinged In testimony whereof, I have signed this to the bracket, said stay bar being provided specification in the presence of tWo subscribwit-h spaced transverse notches and a Wedge ing Witnesses.

block movable through said openings to fit GARNETT FREDERICK NORTON. 5 said notches and provided with a notch Witnesses:
